i noticed today when i was about leavemy house that when i rev my engine a little bit theres a squeaking noise i hear coming from the engine.(btw i know just about nothing about car engines.)could it be a beltor pulleys? if so, do i need to get a new one or what? i have 2002.

 

It could be the belt, they are good for about 50 - 60k miles.

 

Yessr, most likely the belt, mine squeaks a little when idling.
